Overload Monitoring with Resistive Load, V
Description
The IC U4793B in bipolar circuit, is designed to monitor
overload or a short circuit in automotive or industrial
applications. The threshold is tied to V
whereas V
voltage, V
exceeds this value, the output is turned on, otherwise the
output is turned off.
